[ENH] Add general testing for common data `dtypes`

### Describe the issue

Currently we do not test specific data dtypes. We should add a general estimator test converting testing data to common types i.e. float32, float64, int32, int64 and make sure it still runs as expected.

### Suggest a potential alternative/fix

Add new check to the estimator testing in the `testing` module.
